VALVE.

Application filed September 25, 1912.

To all whom it may concern Be it known that I, LEROY S. Prou'rs, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented anew and useful Valve, of which the following is a specification.

My invention relates to improvements in valves and especially to valves used in the handling of milk and cream in creameries, milk depots, ice cream making establishments and the like, the various parts of the valve being so made as to be readily separated from each other for thorough cleaning. Such valves are also frequently used in chemical establishments, and in fact in many different industries where it is desir able to clean containing vessels and valve or pipe connections at frequent intervals and in a thorough manner.

The objects of the invention are to generally improve devices of the character described, to provide a valve of simple, strong and durable construction, to so construct the valve that the cut-off member is located closely adjacent the entrant end of the valve, to provide for the ready disconnection of the various parts for the purpose of cleaning and to so construct the valve that in its practical application it may readily be made of any desired length as circumstances may require or convenience suggest. These objects, together with other objects readily apparent to those skilled in the art, may be attained by the construction illustrated in the accompanying drawings, although the invention may be embodied in other forms, the construction illustrated being chosen by way of example.

In the drawings Figure 1 is a longitudinal, vertical sectional view through a valve embodying my invention showing same connected to the bottom of a vat or tank, and parts being broken away to reduce the size of the figure. Fig. 2 isa front end elevation of the valve. Fig. 8 is a top view of the entrant end of the valve. Fig. 1 is a transverse sectional view on the line 4.4t of Fig. 1. V

Throughout the several views similar reference numerals indicate similar parts.

More specifically describing the construction disclosed in said drawings, the numeral 1 indicates the bottom of a vat or tank adapted to contain liquid to be drawn. oil through the valve.

The numeral 2 indicates generally the entrant member and the numeral 3 the dis charge or spout member. The entrant member comprises the internally frustoconical casing 4t internally ground to receive the correspondingly shaped, externally ground cut-oil member 5. Connected to the casing t is the entrant collar 6 which extends laterally from said casing and is provided with the integral flange and ears 7 for attachment to the bottom 1. Both ends of the casing 41 are open and at the larger end the integral, enlarged internally screw threaded flange 8 is provided to receive the connecting member 9 which member consists of a piece of tubing with external screw threads at its two ends, said tubing being of any desired length in accordance with the requirements.

The discharge member 3 comprises a cylindrical body portion 10 provided at its rear end with the integral, enlarged in ternally screw threaded flange 11 adapted to receive the front end of the member 9 and at its forward end with the outwardly extending externally screw threaded, annular flange 12 provided internally with the beveled, ground head-seat 13. The portion 10 is also provided with the integral discharge collar or spent 1 which may be provided with means for the attachment of sanitary pipe or the like, if desired, the valve in the drawings being; provided with the inner annular recess 1:? adapted to receive an end of such pipe.

The cut-oil member 5 is provided with frusto-conical side walls and a head 16 at the smaller end closes the same, while at the larger endv said cut-off member opens into the member 9. in the side walls of the member 5 is provided the valve opening 17 which, by rotation of the member 5 within the casing 4, may be brought to register with the collar 6, in which condition the valve is open, or may be turned away from said collar, as shown in Fig. 1, when the side walls of the member 5 will close the collar 6. Fixedly connected to the head 16 and extending forwardly through the member 5, member 9 and member 3 is the valve stem 18 preferably provided at its forward end with the fixedly connected valve lever 19 by which said stem may be manually rotated. Mounted upon the stem 18 is the circular head 20, preferably provided with packing "21 to produoe liquid tight but rotatable connection between said head and the stem 18. The head 20 is also provided with the beveled, ground seating face 22 adapted for engagement with the seat 13, and a retaining ring 23 provided with screw threads 24 engaging the screw threads on the annular flange 12 and with an inwardly extending head retaining flange 25 is provided. Said ring may be provided with means such as the knobs 26 for conveniently turning said ring onto and off of the flange 12. Located upon the stem 18 within the member 3 is a coil spring 27 bearing against the head 20 and a pin 28 in the stem 18 to yieldingly hold the cut-off member 5 firmly seated within the casing 4.

Attention should be called to the fact that the internal diameter of the members 9 and 3 is slightly greater than the greatest external diameter of the member 5, and it will be readily apparent from an inspection of Fig. 1 that by unscrewing the retaining ring 23 from the flange 12 the head 20, with the stem 18 and member 5 may be removed, whereupon the members 3, 9 and at will be open for thorough cleaning, as by means of a swab or brush, the rear end of the member 4: being open so as to give free access either from the front or rear end of the valve. The collars 6 and 16 may of course be readily cleaned and the stem 18 and parts connected thereto may also be readily cleaned before replacing.

It should be noted that the valve described is particularly well adapted for use on mixing vats for ice cream making and the like. The batches of material mixed in such vats include sugar, flavors and the like, which have a tendency to settle to the bottom of the tank and in case a valve is used which has a large opening or space intermediate the entrant end and the valve or closing member, such sugar and the like will settle into such space, fail to be mixed with the batch, and will be drawn off in unmixed condition when the valve is first opened. In the con struction herein described, however, the cutofi member is located at the entrant end of the valve and there is no recess of any appreciable extent into which such sugar or other heavy ingredients may enter and escape mixture with the batch.
